Abstract:Since it has been shown that the velocity and temperature distributions of molten metal affect bead geometry, the microstructure and mechanical properties of the weld produced, there has been a significant interest in the quantitative representation of heat transfer and fluid flow phenomena in weld pools. This paper represents a transient Two-Dimensional (2D) axisymmetric model for investigating the heat and fluid flow in weld pools and for determining bead geometry, velocity profile and temperature distributi… Show more
